Proto65 Rev0.1, a 6502 SBC based on Protor5
Introduction
This is the link to Proto65 Rev0, an earlier version without the disk-on-module.
This is the link to Proto65 Rev0.2, a later version with I2C bus added
Protor5 has a prototype area big enough for a processor, RAM and IDE44 interface. In this evolving project a 6502 CPU along with 128Kx8 RAM and an IDE interface are prototyped on a protor5 board.
